3. Diagnostic aids 5021-0XX This chapter explains the tests and procedures to identify printer failures and to verify repairs have corrected the problem. The following diagnostic aids can be initiated at POR by pressing certain button sequences. These tests are also available in diagnostic mode. See "Diagnostic mode" on page 3-4, for more information. Disabling download emulations Error Code 964: Download Emulation CRC Failure. Checksum failure detected in the emulation header or emulation file. To help resolve Download Emulation problems, the following steps are necessary to instruct the printer to POR without activating any download emulations. To disable the download emulation: 1. Turn the printer off. 2. Press and hold the Select and Return buttons. 3. Turn the printer on and release the buttons once "Performing Self Test" displays. After POR completes, the CONFIG Menu is displayed. 4. Select Download Emuls from the menu. 5. Select the Disable Option. The printer automatically exits the configuration menu and initializes as if the download emulator were not installed. Once the printer is idle, a new emulator can be downloaded again. Note: If you power cycle the printer after selecting the disable option, the download emulator will be activated. Diagnostic aids 3-1
